The Readonly module (q.v.) is an effective way to create non-modifiable variables. However, it's relatively slow. The reason it's slow is that is implements the read-only-ness of variables via tied objects. This mechanism is inherently slow. Perl sim...

The Readonly module exports the "Readonly" subroutine, but this subroutine executes at runtime. This module causes it to execute at BEGIN time. Thus: use strict; use warnings; use Readonly; use constant MY_VALUE => 'foo'; Readonly my $MY_VALUE => 'ba...

This simple module can make scalars read-only. Useful to protect configuration variables, for example. This module can also be used to subvert Perl's many read-only variables to potential evil trickery. readonly Ths function takes a scalar variable a...

ARGV::readonly - make <> open files regardless of leading/trailing whitespace and/or control characters such as |, >, amd <.
++

the code is shorter than the documentation. Please look at it. EXPORT None by default. TO DO ideally a suite of ARGV::* modules will appear, each doing their little thing, in a way that they won't stomp on each other's toes. This module has no exclus...

This module provides some syntactic sugar for defining enumerated scalar values. It is to Readonly what the enum package is to constant. Unlike enumerated constants, these scalars can be used as hash keys and interpolated in strings. Unlike enum, onl...

This is a type constraint library for write-restricted references. This module is built with Type::Tiny, which means that you can use it with Moo, Mouse, Moose, or none of the above. Type Constraints This library provides the following type constrain...

This trait makes the tied hash read-only, even if the underlying object's attributes are read-write. Attempts to store to or delete from the hash will throw an error. BUGS Please report any bugs to <http://rt.cpan.org/Dist/Display.html?Queue=Tie-Moos...

This is a simple rule to ensure that "save()" and "remove()" calls to a particular class do not actually do any work. Instead they just result in a warning that the class is read-only. METHODS behavior_factory() Installs the behavior during the class...

This field is used to display but not update data from the database/model. This readonly field has the "readonly" and "noupdate" flags set. The "readonly" flag is a hint to render the HTML as a readonly field. The "noupdate" flag tells Form::Processo...

Creates a read only wrapper around a Config::Hierarchical object. This let's you access the config object as a hash. You can use {} access which makes it easy to use the config in interpolated string. You can also use keys and each on the tied config...

An HTML::Native::Attribute::ReadOnly object is an HTML::Native::Attribute object that does not allow modification of its values. See "DYNAMIC GENERATION" in HTML::Native::Attribute for further details on when and why you might want to use an HTML::Na...

Validation::Class::Directive::Readonly is a core validation class field directive that determines whether the associated parameters should be ignored. AUTHOR Al Newkirk <anewkirk@ana.io> COPYRIGHT AND LICENSE This software is copyright (c) 2011 by Al...

This is a convenience package for use in situations that require you to make modifications to files, even if those files are readonly. Typical scenarios include tweaking files in software build systems, where some files will have been generated that ...

The tie via this module has 2 main behaviors. First, it treats a stack of hashes as a single unit similar to Tie::Proxy::Hash (but without the "translation" mechanism and some other differences) This allows you to have your main hash and then assign ...

Archlinux uses a package manager called pacman. Pacman internally uses the alpm library for handling its database of packages. This module creates a perlish object-oriented interface to the libalpm C library. In the past this module implemented trans...

"Fixed" is a little like Readonly; the main difference is that you can assign to fixed variables. What?! Then how are they fixed? Because you can only assign to them once! use 5.012; use strict; use warnings; use Fixed; fix $x; # declared but not ini...

This "*IS A*" text widget with all bindings removed that would alter the contents of the text widget. The contents can still be modified via method calls. BINDINGS Only read-only bindings from Tk::Text are available in Tk::ROText. Additionally the fo...
